  • iPhone Store Kit returning invalid product ID errors

    - by EToreo
    Hello, I am trying to test In App Purchases on my iPhone and running into a problem where the product IDs I request information for end up being returned to me as invalid product IDs in the "didRecieveResponse" method. I have: Created an in store product associated with this app. It's bundle ID matches everything else. It has been cleared for sale and approved by the developer. Made sure my new provisioning profile has in store app purchases enabled and it has the full app name: "com.domain.appname" Made sure this is the provisioning profile being used to sign the app to my iPhone. Made sure that "com.domain.appname" is the app ID used to build the provisioning profile. Made sure that "com.domain.appname" is used in my plist file as the bundle identifier. Everything seems to be in place, however I still get my products returned to me as invalid IDs. This is the code I am using: - (void)requestProductData { SKProductRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithObject: @"com.domain.appname.productid"]]; request.delegate = self; [request start]; } - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { NSArray *myProducts = response.products; NSArray *myInvalidProducts = response.invalidProductIdentifiers; for(int i = 1; i < myInvalidProducts.count; ++i) { std::cout <<"invalid product id = " << [[myInvalidProducts objectAtIndex:i] UTF8String] << std::endl; } for(int i = 0; i < myProducts.count; ++i) { SKProduct * myProduct = [myProducts objectAtIndex:i]; std::cout << "Product Info:" << std::endl; std::cout << "\tlocalizedTitle = " << [[myProduct localizedTitle] UTF8String] << std::endl; std::cout << "\tlocalizedDescription = " << [[myProduct localizedDescription] UTF8String] << std::endl; std::cout << "\tproductIdentifier = " << [[myProduct productIdentifier] UTF8String] << std::endl; std::cout << "\tprice = " << [[myProduct price] doubleValue] << std::endl; std::cout << "\tpriceLocale = " << [myProduct priceLocale] << std::endl; } [request autorelease]; } All my product IDs show up in the invalid printouts and none of them show up in the "Product Info:" printouts. Any suggestions would be greatly appreciated... P.S. Yes, this is built as Objective-c/c++.

  • iPhone SDK 3.0 and symbolicatecrash not getting along?

    - by Steve
    * UPDATE * I've reinstalled with Snow Leopard, clean install. Completely wiped my existing Leopard install. Same problem persists. I've tried numbers of versions of symbolicatecrash to resolve symbols in my crash reports. From the version provided by Apple, to Alan's Quatermain's version posted on GitHub and finally from http://openradar.appspot.com/6438643. For whatever reason, the best results I can get is for symbols on my own libraries to get resolved. Normally, this is enough data to point me in the right direction -- other times it is not. With 2.x I had no problems getting the symbols for my code + Apple provided libraries from within the stack traces in each thread. Most likely an issue with my environment here, I'm not at all doubting the work that Apple or Alan have done. Yes I'm certain the dSYM I have stashed away is the same exact one that's generating the crash report. Although 'Foo' is me, and getting symbols from it is wonderful, I need to see symbols from the other functions in the stack to truly understand my reports. Note: For devices that crash running the app on iPhone OS 2.2.1, I have no problem getting all symbols. This is an iPhone OS 3.0 issue it appears. Also, while running symbolicatecrash in verbose mode here's a few of the things that struck me as wrong: - NO MATCH NOT searching in Spotlight for dsym with UUID of /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation ## Warning: Can't find any unstripped binary that matches version of /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation ..........fetching symbol file for libobjc.A.dylib--[undef] Searching [/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A345)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A347)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.1 (5B108)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.2 (5C1)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0 (7A341)/Symbols/usr/lib/libobjc.A.dylib]...--[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A345)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A347)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.1 (5B108)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.2 (5C1)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0 (7A341)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH NOT searching in Spotlight for dsym with UUID of /usr/lib/libobjc.A.dylib ## Warning: Can't find any unstripped binary that matches version of /usr/lib/libobjc.A.dylib Here's an example of the crash report after running it through symbolicatecrash: Thread 0 Crashed: 0 libSystem.B.dylib 0x31dc476c 0x31d46000 + 517996 1 libSystem.B.dylib 0x31dc4755 0x31d46000 + 517973 2 Foo 0x00053075 uncaught_exception_handler + 21 3 CoreFoundation 0x3028f65f 0x301fd000 + 599647 4 libobjc.A.dylib 0x30013693 0x3000c000 + 30355 5 libstdc++.6.dylib 0x374ccc2d 0x3748a000 + 273453 6 libstdc++.6.dylib 0x374ccc81 0x3748a000 + 273537 7 libstdc++.6.dylib 0x374ccd4d 0x3748a000 + 273741 8 libobjc.A.dylib 0x300135ff 0x3000c000 + 30207 9 CoreFoundation 0x30222f2d 0x301fd000 + 155437 10 CoreFoundation 0x30222ecb 0x301fd000 + 155339 11 Foundation 0x30521e33 0x30501000 + 134707 12 Foundation 0x30570d47 0x30501000 + 458055 13 Foo 0x0000a1db -[Bar barfoo] (Bar.m:1617) 14 Foo 0x00032f73 -[MyViewController foobar] (MyViewController.m:727) 15 Foo 0x000329b9 -[MyViewController foobar] (MyViewController.m:666) 16 Foo 0x00031fab -[MyViewController tabBar:tabSelected:] (MyViewController.m:440) 17 Foo 0x00068d41 -[TTTabBar setSelectedTabIndex:] (TTTabBar.m:160) 18 Foo 0x00068ca3 -[TTTabBar setSelectedTabView:] (TTTabBar.m:142) 19 Foo 0x000689cf -[TTTabBar tabTouchedUp:] (TTTabBar.m:83) 20 CoreFoundation 0x302552f9 0x301fd000 + 361209 21 UIKit 0x3094d101 0x308ed000 + 393473 22 UIKit 0x3094d0a1 0x308ed000 + 393377 23 UIKit 0x3094d073 0x308ed000 + 393331 24 UIKit 0x3094cdcd 0x308ed000 + 392653 25 UIKit 0x309779c1 0x308ed000 + 567745 26 UIKit 0x30977011 0x308ed000 + 565265 27 UIKit 0x309767d9 0x308ed000 + 563161 28 UIKit 0x30923613 0x308ed000 + 222739 29 UIKit 0x30923163 0x308ed000 + 221539 30 GraphicsServices 0x32045a4d 0x32041000 + 19021 31 CoreFoundation 0x30253041 0x301fd000 + 352321 32 CoreFoundation 0x30252771 0x301fd000 + 350065 33 GraphicsServices 0x32044b0f 0x32041000 + 15119 34 GraphicsServices 0x32044bbb 0x32041000 + 15291 35 UIKit 0x308f0363 0x308ed000 + 13155 36 UIKit 0x308ef121 0x308ed000 + 8481 37 Foo 0x00002097 main (main.m:13)

  • Reciving UDP packets on iPhone

    - by Eli
    I'm trying to establish UDP communication between a MAC OS and an iPod through Wi-Fi, at this point I'm able to send packets from the iPod and I can see those packets have the right MAC and ip addresses (I'm using wireshark to monitor the network) but the MAC receives the packets only when the wireshark is on, otherwise recvfrom() returns -1. When I try to transmit from MAC to iPhone I have the same result, I can see the packets are sent but the iPhone doesn't seem to get them. I'm using the next code to send: struct addrinfo hints; int rv; memset(&hints, 0, sizeof hints); hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_DGRAM; if ((rv = getaddrinfo(IP, SERVERPORT, &hints, &servinfo)) != 0) { fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(rv)); return 1; } // loop through all the results and make a socket for(p = servinfo; p != NULL; p = p->ai_next) { if ((sockfd = socket(p->ai_family, p->ai_socktype, p->ai_protocol)) == -1) { perror("talker: socket"); continue; } break; } if (p == NULL) { fprintf(stderr, "talker: failed to bind socket\n"); return 2; } while (cond) sntBytes += sendto(sockfd, message, strlen(message), 0, p->ai_addr, p->ai_addrlen); return 0; and this code to receive: struct addrinfo hints, *p; int rv; memset(&hints, 0, sizeof hints); hints.ai_family = AF_UNSPEC; // set hints.ai_socktype = SOCK_DGRAM; hints.ai_flags = AI_PASSIVE; // use to AF_INET to force IPv4 my IP if ((rv = getaddrinfo(NULL, MYPORT, &hints, &servinfo)) != 0) { fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(rv)); return 1; } // loop through all the results and bind to the first we can for(p = servinfo; p != NULL; p = p->ai_next) { if ((sockfd = socket(p->ai_family, p->ai_socktype, p->ai_protocol)) == -1) { perror("listener: socket"); continue; } if (bind(sockfd, p->ai_addr, p->ai_addrlen) == -1) { close(sockfd); perror("listener: bind"); continue; } break; } if (p == NULL) { fprintf(stderr, "listener: failed to bind socket\n"); return 2; } addr_len = sizeof their_addr; fcntl(sockfd, F_SETFL,O_NONBLOCK); int rcvbuf_size = 128 * 1024; // That's 128Kb of buffer space. setsockopt(sockfd, SOL_SOCKET, SO_RCVBUF, &rcvbuf_size, sizeof(rcvbuf_size)); printf("listener: waiting to recvfrom...\n"); while (cond) rcvBytes = recvfrom(sockfd, buf, MAXBUFLEN-1 , 0, (struct sockaddr *)&their_addr, &addr_len); return 0; What am I missing?

  • Regarding Sqlite Datbase connectivity in iphone

    - by Prash.......
    hi.. I am developing an application in iphone in which i have to do the database connectivity using sqlite. I have made a "clsDBManage" class which contains 4 functions open_database, close_database, is_database_open, getdatabase_connection, which are globally defined ,i have a screen called "user details" in which i am filling the user details such as name , mobileno , email-id , password, i want that when user feeds the info it should get connected with database and store the details entered and should authenticate the user the next time he logs in.

  • Possible iphone animation timing/rendering bug?

    - by David
    Hi all, I have been working on an iphone apps for several weeks. Now I encounter an animation problem that I can't figure out how to resolve. Mayhbe you can help. Here is the details (a little long, bear with me): Basically the effect I want to achieve is, when user click a button, a loading view pops up, hiding the whole screen; and then the apps does a lot of heavy computation, which takes a few seconds. Once the computation is done, soem result views (something likes checkers on a checker board) are rendered under the loading view. Once all result views are rendered, I used animation animation to remove the loading view nand show the result views to the user. Here is what I do: when user click a button, run this code: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(loadingViewInserted:finished:context:)]; // use a really high index number so it will always on top [self.view insertSubview:loadingViewController.view atIndex:1000]; [UIView commitAnimations]; In the "loadingViewInserted" function, it calls another function doing the heavy computation work. Once the computation is done, a lot of result views (like checkers on a checker board) are rendered under the loading view. for(int colIndex = 1; colIndex <= result.columns; colIndex++) { for(int rowIndex = 1; rowIndex <= result.rows; rowIndex++) { ResultView *rv = [ResultView resultViewWithData:results[colIndex][rowIndex]]; [self.view addSubview:rv]; } } Once all result views are added, following animation is invoked to remove the loading view: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; [loadingViewController.view removeFromSuperview]; [UIView commitAnimations]; By doing this, most of the time (maybe 90%) it does exactly what I want. However, sometime I see some weird result: the loading view shows up first as expected, then before it disappears, some result views, which suppose to be under the loading view, suddenly appears on top of the loading view; and some of them are partial rendered. And then the loading view curled up, and everything looks normal again. The weird situation only lasts for less than a second, but already bad enough to screw up the UI. I have tried all different kinds of thing to fix this (using another thread to remove the loading view, make the loading view non-transparent), but none of them works. The only thing that makes a little better is, I hide all the result views first; after the last animation finished, in its call back, unhide all result views. But this loses the nice effect that when curling up the loading view, the results are already there. At this point, I really think this is a bug in iphone (I compile it with OS 3.0) OS. Or maybe you can point out what I have done wrong (or could do differently). (thanks for finishing this long post, :-) )

  • Yet another UITableView Question

    - by barbgal
    Hi, I have a strange issue in my iPhone application. I have created a UITableView with 4 Sections and 3 Rows so totally 12 Rows.

  • Popping UIView crashes app

However when I remove the UIView to return back to the UITableView the app crashes. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here.

  • iPhone Curl Left and Curl Right transitions

    - by Dimitris
    I am looking for a way to do a UIViewAnimationTransitionCurlUp or UIViewAnimationTransitionCurlDown transition on the iPhone but instead of top to bottom, do it from the left to right (or top/bottom in landscape mode). I've seen this asked aroud the internet a few times but none sems to get an answer. However I feel this is doable. I have tried changing the View's transform and the view.layer's transform but that didn't affect the transition. Since the transition changes when the device changes orientation I presume there is a way to fool the device to use the landscape transition in portrait mode and vice versa?

  • How to convert CFDataRef data to UIImage / NSData - Iphone

    - by sagar
    Hello ! every one. I am having a little query regarding CFData in Objective C / iPhone Development. See, Apple documentation has following method for CGPDFStream CGPDFStreamCopyData(<#CGPDFStreamRef stream#>, <#CGPDFDataFormat *format#>) Above method return type is CGDataRef. I have data as stream. Now I wish to convert in image. & For that I think I should follow this way. CGPDFDataFormat t=CGPDFDataFormatJPEG2000; CFDataRef data = CGPDFStreamCopyData (stream, &t); After executing above statements - I have some reference in data variable. Now my Query is - How to convert this CFData to NSData or UIImage ? I have gone through the documentation of apple - But I am failure to find it. Thanks in advance for sharing your knowledge. Sagar

  • iPhone Horizontal Scrolling Table

    - by Wireless Designs
    Hello all - I need to create a view on the iPhone that scrolls horizontally through a gallery of images. The issue is that this gallery has the potential to have 100s to 1000s of images that needs to be presented, so I would like to avoid loading them all into a single UIScrollView at once and destroying performance. I need to create a view that recycles the view objects (like UITableView) to increase performance and reduce memory overhead, but it needs to scroll in a horizontal fashion. Any ideas? Is it possible to make UITableView operation horizontally? Thanks!

  • iPhone Gameloop render update from a separate thread

    - by Rich
    Hi, I'm new to iPhone development. I have a game loop setup as follows. (void)CreateGameTick:(NSTimeInterval) in_time { [NSThread detachNewThreadSelector:@selector(GameTick) toTarget:self withObject:nil]; } My basic game tick/render looks like this (void)GameTick { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; CGRect wrect = [self bounds]; while( m_running ) { [self drawRect: wrect]; } [pool release]; } My render function gets called. However nothing gets drawn (I am using Core Graphics to draw some lines on a derived UIView). If I call my update via a timer then all is well and good. Can you tell me why the render fails when done via threads? And is it possible to make it work via threads? Thanks Rich

  • iPad/iPhone duplicate view and resize?

    - by MidnightLightning
    I'm working on an app that is similar to a Presentation application (Keynote/Powerpoint) for the iPad, that will use the VGA adapter to present on screen. However, if the presenter is using the external display for the presentation, I'm wondering if it's possible to have a miniature version of what's on the external display show up on the main iPad display (along with the presentation controls, which will take up most of the screen). In other words, I'm looking for a way with the iPhone SDK to "bake" the contents of a View (which will contain various Images and Labels in various locations) to an image (or some other static storage), resize it, and re-display it in another view. It would need to be smaller (since I don't want the 1024x768 external display to completely overlay the iPad's main display, only a corner of it), and either live-updating (literally an instance of the other View, just scaled), or be able to be refreshed, such that when updating the external display, the "picture in picture" version of itself would be updated too.

  • New to iPhone SDK: touchesBegan not called

    - by coriolan
    Hi, I created a very very basic iPhone app with File/New Projet/View-Based application. No NIB file there. Here is my appDelegate .h @interface MyAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MyViewController *viewController; } .m - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } And here is my loadView method in my controller - (void)loadView { CGRect mainFrame = [[UIScreen mainScreen] applicationFrame]; UIView *contentView = [[UIView alloc] initWithFrame:mainFrame]; contentView.backgroundColor = [UIColor redColor]; self.view = contentView; [contentView release]; } Now, in order to catch the touchesBegan event, I created a new subclass of UIView: .h @interface TouchView : UIView { } .m - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"Touch detected"); } and modified the second line in my loadView into this : TouchView *contentView = [[UIView alloc] initWithFrame:mainFrame]; Why is touchesBegan never called?

  • Audio recording error kAudioQueueErr_CannotStart on iPhone OS 3.0

    - by Jeremy Borden
    I'm working on a couple different iphone apps that both record and play sounds concurrently. Think multitrack mixing... play one sound a save it then listen to that sound while recording the next sound to another file. My mechanism for this has been to start up two different audio queues, one for recording, and one for playing. This was working A-OK until the release of OS 3.0... Since then, however, the following happens: If I start the recording queue first, it supposedly starts fine, but the call to AudioQueueStart for the playback queue returns kAudioQueueErr_CannotStart. If I start the playback queue first, it also supposedly starts fine, but the call to AudioQueueStart for the record queue returns the same error, kAudioQueueErr_CannotStart. Anyone have any luck debugging this error? Seems like maybe the two queues are stomping on each other's memory or something? The official description is: "The audio queue has encountered a problem and cannot start." Not super helpful... Jeremy

  • Constant opacity with glBlendFunc on iPhone

    - by Jeff Johnson
    What glBlendFunc should I use to ensure that the opacity of my drawing is always the same? When I use glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) and multiple images are drawn on top of each other, the result is more and more opaque until it's completely opaque after a certain number of imgaes. The closest I have come is to use glBlendFunc(GL_ONE_MINUS_DST_ALPHA, GL_ONE_MINUS_SRC_ALPHA) which maintains a constant opacity no matter how many images are on top of each other, although there is a slight variation in opacity if the images overlap each other. Any other render states I should consider trying? Any other ideas? I am making a drawing app for my kid and I don't want the images (brush) they draw to cover up the background. Heres the closest I've got: I want to have it so that the overlap part of the circles is the same color and opacity as the center part of the circle. I am using cocos2d iphone v. 0.99

  • Embedding an offline Dashcode application in a UIWebView in an iPhone application

    - by Nimrod
    In order words, can anyone tell me the basics of how to create a "hybrid" iPhone application? I want to load the web content (the Dashcode app itself) from the native application's application bundle. I've gotten this to partially work, but some content won't display and it otherwise seems like Dashcode is assuming a certain Safari environment or something that I don't seem to have in my UIWebView. Can anyone provide a link to some sample code that embeds a Dashcode project into a cocoa touch Xcode project? (I did search around Google for a bit trying to find something and I failed to come up with anything worthwhile, except for some books that I might eventually buy if the approach seems worthwhile.)

  • iphone google maps crosshair button

    - by xastor
    I would like to use or emulate a button like the gps button in the bottom left corner of the standard maps application on the iphone OS. The button behaves like a toggle button where gps is enabled or disabled depending on whether it is pushed and it may hold a small spinner component while the gps is finding your position. Does anyone know if this component can be easily constructed using default components? If no, what would be the best way to develop such a component? Is the crosshair/target icon a generic icon that I can re-use?

  • Object mapping in objective-c (iphone) from JSON

    - by freshfunk
    For my iPhone app, I'm consuming a RESTful service and getting JSON. I've found libraries to deserialize this into an NSDictionary. However, I'm wondering if there are any libraries to deserialize the JSON/NSDictionary/Property List into my object (an arbitrary one on my side). The java equivalent would be the object-relational mappers although the sort of object mapping I'm looking for is relatively straightforward (simple data types, no complex relationships, etc.). I noticed that Objective-C does have introspection so it seems theoretically possible but I haven't found a library to do it. Or is there a simple way to load an object from an NSDictionary/Property List object that doesn't require modification every time the object changes? For example: { "id" : "user1", "name" : "mister foobar" "age" : 20 } gets loaded into object @interface User : NSObject { NSString *id; NSString *name; int *age; }

I need to put them down on paper so I can relay my designs to others in my team. I was wondering what the best on-line gui mockup tool I could use? I have a lot of experience with Visio and I truly like it. I want a tool that would be web based so I could collaborate with others on the team. Does anyone have a suggestion for an easy gui mockup tool that I could use?

  • iphone dev: UIImageview subclass interface builder - how to call custom initializer

    - by ninjasmith
    hi. I messing with iphone developement. I have a uiimageview subclass that I want to use to detect touches. I have sucessfully added to interfacebuilder and I can detect a touch in my UIImageview subclass within my application so all is good on that front. however my UIImageView subclass has a custom initializer which is not called when it is created in interface builder. if I manually initialize the UIImageview and add it programmatically I think it will work but then I lose the ability to 'see' my positioning in Interface builder. how can I either 1) 'see' a uiimageview in interface builder that is added in code? (not possible?) 2) call my custom initializer when the subclass is instantiated in interfacebuilder. thanks
